TRANSFER MEGHANISM FOR LAP-WELD TUBING.

Application filed January 29, 1915.

Y fo all 'zu/0m t may concern.'

Be it known that I, DANIEL lVoon` SIDE, a citizen of the United States,residing at Youngstown, in the county of Maliening and State of Ohio,have invented new and useful Improvementsin Transfer Mechanism forLap-Weld Tubing, of whichV the following is a specification.

My invention relates to mechanism for Ytransferring lap-weld tubingsidewise from one welding-trough over an adjacent welding-trough. v

It is the object of my invention to provide a simple mechanism by whichtubing in one of two parallel troughs at the rear end of a lap-weldfurnace may he transferred sidewise over the other welding-trough.Heretofore it has been common to provide arms for lifting the tubes outof one trough and carrying them over the other trough. I have simplifiedthe mechanism-by bodily lifting or swinging one welding-trough with atube thereon over the other weldingtrough.

My invention further consists in details of the mechanism whereby thetroughs are supported and operated.

Referring to the accompanying drawings, Figure 1 is a plan of one end ofa pair of welding-troughs equipped with my invention; Fig. 2, across-section on the line Hull, Fig. 1; Fig. 3, a side elevation of asecond form of my invention with parts broken away; Fig. e, across-section on the line ITL-IV, Fig. 3; Fig. 5, a cross-section on theline v V, Fig. 3; and Fig. 6, a cross-section on a reduced scale on theline VI-VI, Fig. 3.

Referring first to Figs. 1 and 2, 1 and 2 represent a pair ofwelding-troughs for re ceiving pipes as they are dischargedV from thewelding rolls situated at the rear end of a. lap-weld furnace. I havenot illustrated the furnace and rolls as they are well known inconnection with pairs of weldingtroughs located as above described. Theweldingtrough 1 normally rests on the top of pillars near the ends ofthe trough, one pillar 3 being shown. The trough is secured to therock-shaft l which is parallel with the trough and supported by thepillars 3. To one side of the trough 1 I pivotally connect Vone end ofthe tilting skids 5, which have Specification of Letters Patent.

Serial No. 5,109.

.lVhen it is desired to transfer the pipe 11 from the trough 1 to theskids, the motor 10 is operated to cause the trough 1 to move from itsfull-line position to its dotted position (Fig. 2), whereupon the pipe11 rolls out of the troughV 1, as shown on Fig. 2, and down the skids 5to the skids 6, on which a pipe 12 is shown. The welding-trough 2 1sarranged at that side of the trough 2 which is opposite the skids 5. Itsends are supported by the legs 13, having the curved arms 14 connectedto the rock-shaft 15. These arms 14 have their curves extendingdownwardly from the troughs and then upwardly in the form of the letterU, one leg of the U bearing the trough and the other being connected tothe shaft 15. The curves are so shaped that the trough 1 is in the samewhen'the trough 2 is swung up on the shaft 15 to the dottedposition.(Fig. 2). The shaft 15 is provided with the arm 16 having itsouter end pivoted to the links 17, to which the piston rod 18 of thehydraulic or other motor 19 is pivoted.

Referring now to Figs. 3 to 6, the parts thereon corresponding infunction to parts on Figs. 1 and 2 have the same reference numerals ason Figs. 1 and 2 with the eX- ponent letter a. The rock-shaft 15n hasits ends mounted in the housings 20 and is provided with the collar 21keyed thereon. The collar has the opposite arms 16a and 16", the formerbeing connected by the links 17 to the pistonerod or plunger 1Sat of themotor 19a, and the latter being connected by the links 17b to thepiston-rod or plunger 18b of the motor 19h. To the shaft 15a are keyedVthe collars 22 which carry the arms 14a, supporting at their outer endsthe legs 13a. The trough 2n is supported on the top of these legs, whichrest normally on the block 23 on the bed 24: of the apparatus. Therock-shaft la is secured to the trough 1au which is between the shaft 4and the trough 2, To the arm 7a on the shaft 4a, carried by the bearings29, I secure the upper end of the links 8a, the lower end of the linksbeing connected to the arm 25 on the collar 26 which is loosely mountedon the shaft 15a. This collar carries the opposite arms 27 and 28, theformer being linked to the piston rod or plunger' 9a of the motor 10 andthe latter being linked to the piston-rod or plung'er 9b of the motor10b. When it is desired to discharge a pipe in the trough l2L upon theskids 6a (only one shown) the motor 10a is operated which causes theplunger 9ZL to oscillate on the sha-ft 15a toward the right, therebylifting the arm 25, the links 8a and the arm 7u. The lifting of the arm7 oscillates the shaft 4 so as to cause the trough 1a to be swung upover the shaft on the dotted lines above the same (F ig. 4) and todischarge the pipe therein upon the said skids. The trough is returnedto its normal position by the motor l()h through the plunger 9b, the arm28, the collar 26, the arm 25, the links 8, the arm 7a, and the shaft4a. When it is desired to discharge a pipe in the trough 2a upon theskids 6a, the motor 19n is operated, causing the plunger 18, the links17a, and the arm 16a to rise. The upward movement of the arm lbaoscillates the shaft l5 toward the left, `thereby causing the collars 22keyed on the shaft to lift the arms 14 together with the legs 13a andthe trough 21% The latter moves up on the dotted lines (Fig. Ll) on anarc having its center on the shaft l5, the radius of this arc beingsufficiently long to allowy the trough 2a to pass over the trough ln anddischarge a pipe therein upon the' skids 6a in the same manner that thetrough 2 passes over the troughl and discharges the pipe 11 therein uponthe skids 6;; The trough 2a is returned to` normal position by the motorf trough so as to pass over the second ltrough.

and discharge a pipe therein on the opposite side of the second trough.

2. A pair of welding-troughs arranged side by side, a receiving tablearranged at the outer side of one trough, means for-tilting the saidtrough and discharging a pipe in the said trough upon the table, andmeans movable relatively to the said trough` for lifting the othertrough over Ithe said tilting trough and discharging a pipe in thesecond trough upon the table.
